Towards html case
Thinking… (WIP)…
I want to create IDs in programming languages that contain HTML formatting.
For example, here is the formatted id “Collect”.
<sub style="border-color: var(--border-color);">
<font style="border-color: var(--border-color); font-size: 7px;">
Collect
</font>
</sub>
We learned to respect case in programming languages. Hence, we conclude that we should respect formatting in new programming languages.
In this case, the bare ID Collect should be considered to be different from the above ID.
The old ASCII rule - that an ID can contain no whitespace - doesn’t apply to the above.
How do we parse such IDs?
CFGs and REGEX can’t do this job.
One possibility for parsing, is to use OhmJS/PEG to tokenize incoming text and to wrap some sort of marker brackets around each “token”.
For example, we might tokenize the above as
❲
<sub style="border-color: var(--border-color);">
<font style="border-color: var(--border-color); font-size: 7px;">
Collect
</font>
</sub>
❳
where the stuff between the Unicode brackets ❲...❳ is considered to be a whole ID token. Such IDs are the same only if they match character by character. ❲Collect❳ is considered to be a different ID from the above formatted text.
Below is a specific example of what I’m working on at this moment:
ė
<sub style="border-color: var(--border-color);">
<font style="border-color: var(--border-color); font-size: 7px;">
Collect
</font>
</sub>
<br style="border-color: var(--border-color);">
p.wallet += m.wallet
<br style="border-color: var(--border-color);">
m.wallet = 0
<br style="border-color: var(--border-color);">
⇒
I expect it to be tokenized as:
❲ė❳
❲<sub style="border-color: var(--border-color);">
<font style="border-color: var(--border-color); font-size: 7px;">
Collect
</font>
</sub>❳
❲<br style="border-color: var(--border-color);">❳
❲p.wallet += m.wallet❳
❲<br style="border-color: var(--border-color);">❳
❲m.wallet = 0❳
❲<br style="border-color: var(--border-color);">❳
❲⇒❳
In this particular case, ❲ė❳ is a marker that is followed by an ID and then a bunch of formatted text. The ID is:
❲<sub style="border-color: var(--border-color);">
<font style="border-color: var(--border-color); font-size: 7px;">
Collect
</font>
</sub>❳
and the rest of the text is
❲<br style="border-color: var(--border-color);">❳
❲p.wallet += m.wallet❳
❲<br style="border-color: var(--border-color);">❳
❲m.wallet = 0❳
❲<br style="border-color: var(--border-color);">❳
❲⇒❳
I can use OhmJS to tokenize in this manner. Are there any other existing tools that already do what I want? Can this suggested tokenizing format be altered to make parsing easier?
